FEED-WATER STRAINER FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent N 0. 661,931, datedNovember 13, 1900. Application filed March 3, 1900. Serial No. 7,186.(No model.)

. T0 00% whom it may concern:

Be it known that I, JOSEPH P. HAYES, a citizen of the United States,residing at Moloerly, Randolph county, Missouri, have invented certainnew and useful Improvements in Feed-Water Strainers for Locomotives, ofwhich the following is a specification.

My invention relates to that class of strainers which are adapted to beused in connection with a feed-water tank or strainer of a locomotive tointercept particles of foreign matter and prevent them from passing fromthe feed-tank to the injector of the locomotive-boiler, all of whichwill more fully hereinafter appear.

The principal object of the invention is to provide a simple,economical, and efficient feed-water strainer for a locomotive; and theinvention consists in the features, combinations, and details ofconstruction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal sectionalelevation taken on the line 1 of Fig. 2, and Fig. 2 a plan view shownpartly in section.

In the art to which this invention relates it is well known that thewater as supplied to the tanks for locomotives is full of impuritiesthatis, full of pieces of coal and other sedimentswhich it is desirable toremove from such water in as economical a manner as possible before itpasses through the injector into the locomotive. Various devices havebeen provided to accomplish this result, all of which are more or lessdefective in that they are complicated and comparatively expensive tobuild, and, further, that they do not remove all of the sediment orparticles.

To obviate the above objections and provide a simple, economical, andefficient feed water strainer for a locomotive is the principal objectof my invention.

In describing and illustrating my invention I have only shown anddescribed those parts which I consider to be new and in such a mannor asto disclose the invention and enable those skilled in the art topractice the same, leaving out of consideration all the other andwell-known parts which, if shown and described herein, would only tendto prolixity, confusion, and ambiguity.

In constructing a strainer in accordance with my improvements I preferto make a body portion composed of two partsA.the main or bowl-shapedportion and A the cap or upper portion. These parts are formedseparately and provided with flange portions a, arranged in a horizontalplane and adapted to be secured together by means of bolts or cap-screwsct. The lower part or bowlshaped portion is provided with an inlet B,adapted to receive a pipe or hose, which in turn is secured with thefeed-water tank. The cap portion is provided with an outlet B, to whichan outlet-pipe b may be secured and attached to the injector of thelocomotive. The inlet-opening of the bowl-shaped portion is arranged aconsiderable distance above the bottom of the same, so that as the waterenters into the bowl it will pass across the same, contact the wallsthereof, and form a sort of eddy which will permit the sediment andlarge heavy particles to settle in the bottom portion of a waste-chamber0?. The bottom portion of the chamber is provided with an opening inwhich is inserted a plug 0, which may be taken out whenever it isnecessary to withdraw the sediment and foreign particles.

It is desirable that the sediment, large and heavy particles, should beprevented from passing out through the outlet-pipe, and in order toaccomplish this result a strainer D is provided, preferably formed of adisk of perforated copper, which is secured in position between the twoparts of the strainer, as shown particularly in Fig. 1. It will benoticed that this strainer is in a horizontal plane-that is, the sameplane as the inlet and outlet pipes are arranged in-so that the foreignparticles do not directly contact the strainer. This arrangement of theparts permits the strainer to be kept measurably clean and prevents thesediment which has been deposited from being continually stored up.

In securing the perforated or recticulated strainer portion properinposition I prefer to provide the plane surface of each of the flangeswith a series of corrugations a into which the outer portion of thestrainer may pass, which when clamped in position acts as a gasket.

In order to increase the efficiency of the complete strainer, it isdesirable that it be secured to some portion of the locomotive at apoint considerablybelow the feed'water tank and below the injector. Thisarrangement is desirable for the reason that the strainer will beconnected With the feed-Water tank by means of a hose and with theinjector by means of a pipe, so that if the connectionbetween thestrainer and the tank should rot and foreign particles should enter theywould be carried into the strainer and separated from the water. Inorder to accomplish this result, I prefer to provide the cap portion ofthe strainer with an upwardly-projecting lug E, which lug should beprovided with a strap (not shown) and connected with the under side ofthe end beam of the locomotive, thus insuring the keeping of thestrainer at a point below the feed-Water tank and the cleansing of allwater as it passes from the feed-water tank to the injector.

I have not thought it necessary to show either the feed-water tank orthe locomotive, as the simple description thereof which I havehereinabove given will enable those skilled in the art to understand theexact position at which the mechanism is to be secured and theadvantages thereof.

I claim In a strainerof the class described, the combination of a bodyportion made in two parts the lower or main portion provided with aninlet-opening, a waste-chamber below theinlet-opening and a screw-plugfor opening and closing the waste-opening of the waste-chamber the upperpart provided with an outletopening, and a lug for securing the strainerto the end beam of a locomotive, and a piece of perforated orreticulated material forming the strainer proper secured in position andin a horizontal plane between the two parts of the body portion,substantially as described.
